技术领域
本申请涉及空调技术领域，特别是一种均流板及空调室内机及空调室内机的制造方法。
背景技术
目前，传统空调器室内机结构，根据风机的出风方式分为吹风式和吸风式，从风机风口吹出的风先经过换热器(实现冷/热量交换的部件)再从机组出风口出去的方式为吹风式，从风机风口吹出的风不经过换热器，直接从机组出风口出去的方式为吸风式。吹风式出风方式的机组由于风直接拍打在换热器上，换热器上存在局部风速大，且换热器的摆放方式如果与机组成一定角度安装，则风通过换热器时的风向与换热器上的翅片方向不是水平的，容易刮擦翅片，引起风吹翅片异常声，特别是商用天井机，风向与翅片方向是有一定角度的，且由于空间的限制，换热器与风机之间的距离较近，当换热器上出现局部风速大的情况，更容易产生音质异常。该异常声的出现容易分散人的注意力，使人烦躁，客户感受不好。
